ECO GMC ENVOY DENALI 2007 Owners Manual

3. Start on the outside edge of the soil and
gently rub toward the center. Continue
cleaning, using a clean area of the cloth
each time it becomes soiled.
4. Continue to gently rub the soiled area until
the cleaning cloth remains clean.
5. If the soil is not completely removed, use a
mild soap solution and repeat the cleaning
process that was used with plain water.
If any of the soil remains, a commercial fabric
cleaner or spot lifter may be necessary. When a
commercial upholstery cleaner or spot lifter is to be
used, test a small hidden area for colorfastness
rst. If the locally cleaned area gives any
impression that a ring formation may result,
clean the entire surface.
After the cleaning process has been completed,
a paper towel can be used to blot excess moisture
from the fabric or carpet.Leather
A soft cloth dampened with water may be used to
remove dust. If a more thorough cleaning is
necessary, a soft cloth dampened with a mild soap
solution can be used. Allow the leather to dry
naturally. Do not use heat to dry. Never use steam
to clean leather. Never use spot lifters or spot
removers on leather. Many commercial leather
cleaners and coatings that are sold to preserve
and protect leather may permanently change
the appearance and feel of your leather and are
not recommended. Do not use silicone or
wax-based products, or those containing organic
solvents to clean your vehicle’s interior because
they can alter the appearance by increasing
the gloss in a non-uniform manner. Never use
shoe polish on your leather.

Instrument Panel, Vinyl, and Other
Plastic Surfaces
A soft cloth dampened with water may be used to
remove dust. If a more thorough cleaning is
necessary, a clean soft cloth dampened with a
mild soap solution can be used to gently remove
dust and dirt. Never use spot lifters or removers
on plastic surfaces. Many commercial cleaners and
coatings that are sold to preserve and protect
soft plastic surfaces may permanently change
the appearance and feel of your interior and
are not recommended. Do not use silicone or
wax-based products, or those containing organic
solvents to clean your vehicle’s interior because
they can alter the appearance by increasing
the gloss in a non-uniform manner.
Some commercial products may increase gloss on
your instrument panel. The increase in gloss
may cause annoying reections in the windshield
and even make it difficult to see through the
windshield under certain conditions.
Care of Safety Belts
Keep belts clean and dry.
{CAUTION:
Do not bleach or dye safety belts. If you
do, it may severely weaken them. In a
crash, they might not be able to provide
adequate protection. Clean safety belts
only with mild soap and lukewarm water.
Weatherstrips
Silicone grease on weatherstrips will make them
last longer, seal better, and not stick or squeak.
Apply silicone grease with a clean cloth. During
very cold, damp weather frequent application may
be required. SeeRecommended Fluids and
Lubricants on page 517.
485

Washing Your Vehicle
The paint nish on the vehicle provides beauty,
depth of color, gloss retention, and durability.
The best way to preserve the vehicle’s nish is to
keep it clean by washing it often with lukewarm
or cold water.
Do not wash the vehicle in the direct rays of the
sun. Use a car washing soap. Do not use
strong soaps or chemical detergents. Be sure
to rinse the vehicle well, removing all soap residue
completely. Approved cleaning products can
be obtained from your dealer. SeeVehicle
Care/Appearance Materials on page 490.Donot
use cleaning agents that are petroleum based,
or that contain acid or abrasives. All cleaning
agents should be ushed promptly and not
allowed to dry on the surface, or they could stain.
Dry the nish with a soft, clean chamois or an
all-cotton towel to avoid surface scratches
and water spotting.
High pressure car washes may cause water to
enter the vehicle.
Cleaning Exterior Lamps/Lenses
Use only lukewarm or cold water, a soft cloth and
a car washing soap to clean exterior lamps
and lenses. Follow instructions underWashing
Your Vehicle on page 486.
Finish Care
Occasional waxing or mild polishing of your
vehicle by hand may be necessary to remove
residue from the paint nish. You can get
GM-approved cleaning products from your dealer.
SeeVehicle Care/Appearance Materials on
page 490.
If your vehicle has a “basecoat/clearcoat” paint
nish, the clearcoat gives more depth and gloss to
the colored basecoat. Always use waxes and
polishes that are non-abrasive and made for a
basecoat/clearcoat paint nish.
Notice:Machine compounding or aggressive
polishing on a basecoat/clearcoat paint
nish may damage it. Use only non-abrasive
waxes and polishes that are made for a
basecoat/clearcoat paint nish on your vehicle.
486

Foreign materials such as calcium chloride and
other salts, ice melting agents, road oil and tar,
tree sap, bird droppings, chemicals from industrial
chimneys, etc., can damage your vehicle’s nish if
they remain on painted surfaces. Wash the vehicle
as soon as possible. If necessary, use non-abrasive
cleaners that are marked safe for painted surfaces
to remove foreign matter.
Exterior painted surfaces are subject to aging,
weather and chemical fallout that can take their toll
over a period of years. You can help to keep
the paint nish looking new by keeping your
vehicle garaged or covered whenever possible.
Protecting Exterior Bright Metal Parts
Bright metal parts should be cleaned regularly
to keep their luster. Washing with water is all
that is usually needed. However, you may
use chrome polish on chrome or stainless steel
trim, if necessary.
Use special care with aluminum trim. To avoid
damaging protective trim, never use auto or
chrome polish, steam or caustic soap to clean
aluminum. A coating of wax, rubbed to high polish,
is recommended for all bright metal parts.
Windshield, Backglass, and Wiper
Blades
If the windshield is not clear after using the
windshield washer, or if the wiper blade chatters
when running, wax, sap or other material may
be on the blade or windshield.
Clean the outside of the windshield with a
full-strength glass cleaning liquid. The windshield
is clean if beads do not form when you rinse it
with water.
Grime from the windshield will stick to the wiper
blades and affect their performance. Clean
the blade by wiping vigorously with a cloth soaked
in full-strength windshield washer solvent. Then
rinse the blade with water.
Check the wiper blades and clean them as
necessary; replace blades that look worn.
487

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected
from short circuits by a combination of fuses
and circuit breakers. This greatly reduces
the chance of res caused by electrical problems.
Look at the silver-colored band inside the fuse.
If the band is broken or melted, replace the fuse.
Be sure you replace a bad fuse with a new
one of the identical size and rating.
If you ever have a problem on the road and don’t
have a spare fuse, you can borrow one that has the
same amperage. Just pick some feature of your
vehicle that you can get along without — like the
radio or cigarette lighter — and use its fuse, if it is
the correct amperage. Replace it as soon as
you can.
Engine Compartment Fuse Block
The fuse block is located under the hood in the
engine compartment on the driver’s side of
the vehicle. SeeEngine Compartment Overview
on page 390for more information on location.
Remove the primary cover by pressing the
two locking tabs. Remove the secondary cover
by snapping off while lifting. To reinstall the
fuse panel cover, reverse the sequence.

Maintenance Schedule
Introduction
Important: Keep engine oil at the proper level
and change as recommended.
Have you purchased the GM Protection Plan? The
Plan supplements your new vehicle warranties.
See your Warranty and Owner Assistance booklet
or your dealer for details.
Maintenance Requirements
Notice:Maintenance intervals, checks,

Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep
your vehicle in good working condition, but also
helps the environment. All recommended
maintenance is important. Improper vehicle
maintenance can even affect the quality of the air
we breathe. Improper uid levels or the wrong
tire ination can increase the level of emissions
from your vehicle. To help protect our environment,
and to keep your vehicle in good condition, be
sure to maintain your vehicle properly.
Using the Maintenance Schedule
We at General Motors want to help you keep your
vehicle in good working condition. But we do
not know exactly how you will drive it. You may
drive very short distances only a few times a week.
Or you may drive long distances all the time in
very hot, dusty weather. You may use your vehicle
in making deliveries. Or you may drive it to
work, to do errands, or in many other ways.
Because of all the different ways people use their
vehicles, maintenance needs vary. You may
need more frequent checks and replacements.
So please read the following and note how
you drive. If you have any questions on how to
keep your vehicle in good condition, see your
GM Goodwrench
®dealer.
